Hello! I am quit new to play Shadow Priest and I was looking for tips and pointers. I end up dying first most of the time and putting out no to low damage (not even getting a dot up at times). Right now I am playing 2's with a warlock (demo) so anything specifically related to that would be awesome as well.

If your playing 2s with a lock it will be pretty rough as you get little to no peels, trying playing 2s with a resto shaman, frost mage, rogue or feral druid and it should go much smoother, since they will be able to peel and you can burst during stuns.
